jetstar online pissed me off

I tried to book a ticket from sydney to melbourne, after completing all the details and card information and being submitted... an error occured which said to start over.. i started over and submitted again the same message occurs to start over. so I gave up with jestar and booked another flight with tigerairways.. for my surprise when i opened my mail I could see both the iteneries from jetstar and tigerairways. I asked for refund from jetstar as it was their website not functioning well, they asked me to wait for another 7 to 10 days for a response. WOW.. 10 days and I will be in melboune with my creditcard stuck with $400 less to spend.
